Google Play Service , Using Updated Google Map V2

Google Play Service , Using Updated Google Map V2

i am using google play services in my project, i am trying to use google
map v2 service in my app.
For this i included play services as dependency in build.gradle file as
mentioned in this thread.
for now the latest version of play services is 3.2.65 and i am pointing to
it. Ok. So my question is ,In the future when google releases newer
version of play services and the device has play services version above
3.2.65 which was specified in build.gradle file, will cause any problem or
not? And will my application adapts the latest feature of play services
automatically or i have to release updates of my application every time
google releases newer version of play services.
And if not then is there any other way or including play services in
module dependency so that my application will always use updated version
of play services.
Thanks
